Re: Weird rattling sound & humming sound
Bro Elginlye
I went to my usual garage and they were laughing at my prob haha..my old rex did not have this kinda prob and my bmw starts giving this type of weird noise. anyway cut the story short, i did what u did and guess what, the rattling sound went away! amazing that a simple tightening solved the irritating rattling.
Am really grateful to u for sharing your solution : ) I will be monitoring the next few days to see if it comes back. Drove the whole day without the noise so far...

Reasoning? During low rpm n moving off/ coming to a stop, engine block vibrates more, causing loose parts to rattle.
Ask PML to tighten the screws/nuts.
Was also advised to idle for >= 1 min after cold start, e.g. in the morning, or after 8 hrs parked. To allow engine oil/lubricants to circulate b4 moving off. It does make for a smoother drive, less whining sound. A preventive maintenance measure.
